U3 U shaped led corn bulbs are aptly named, because they resemble an ear of corn or corn on the cob. Instead of individual corn niblets, the cob is comprised of individual LED lights which can number between 80 and 108 lights, depending upon the size and style of the bulb. U3 U shaped LED corn bulbs can be used in table lamps, floor lamps and wall sconces. They’re perfect retrofit replacement light sources for many indoor and outdoor applications: parking lots, post top lights, street and pathway lights, security lighting, high bay fixtures, wall packs, and droplights. The extreme brightness of these lights makes them ideal for use in vanity mirrors in bathrooms where you want to be able to see things clearly.
